Humoral and cellular immunogenicity of the HZ vaccine. (a) Levels of anti-glycoprotein (gp) VZV IgG antibody. GMC and GMFR are shown under the figure. (b) The number of VZV stimulated IFN-γ spot-forming cells (SFCs) before and after vaccination. HZ, herpes zoster; gp, glycoprotein; VZV, varicella zoster virus; GMC, geometric mean concentrations; GMFR, geometric mean fold rise.
